But ignoring that special lab, the best way to build or verify a model is with a graph. Let’s look at the constant velocity cart again. Say that the cart starts at time t = t 0 and position x = x 0.

The cart then detects motion over these lines to give position-time data. Again using the quadratic fit I can find the acceleration. In this case it gives a value of 0.1092 m/s 2 .

The velocity at a particular instant is equal to the slope of the tangent drawn on position-time graph at that instant. 3.Average acceleration is the change in velocity divided by the time ...
